  1. Thanks! The Next Generation Science Standards (NGSS) will be released at the end of the month. States that adopt these standards will use them to plan the their instruction from grades K-12. I am creating these videos mainly for teachers of science to give them background on What science they should teach and When they should teach them. Hope that helps. -Paul

  2. Clouds are water droplets suspended. I was trying to motion to a non-cloud portion of the sky but was probably unsuccessful. Thanks for the clarification.

  3. I am far from an "authority". I wanted to understand the new standards and so I created the video series. Hope this helps.

  4. Just a point of clarification, at 0:26 you showed a picture of a cloud to represent water in the vapor or gas phase, but if we can see the cloud then that is actually water droplets in the liquid phase that are suspended in the atmosphere not really in the gas phase.  I just make the point because when we try to help students grasp a particle model for the gas phase, water droplets do not mesh with our model of what water in the gas phase "looks like".  This is not a huge issue but I think we as chemistry teachers need to be aware of the limitations of trying to show representations for gases in our daily lives since most of these gases are colorless an non-visible.  Thank you for sharing your GREAT videos.

  5. im trippin on acid tryna figure out what was acid and it legit led me all the way here. acid drug = drug= medicine = is science = physics so on and so forth

  6. Read my article "Compressible Droplet Atom Structure Theory" – type "H. Tomasz Grzybowski" in Google, get into Research Gate, click on "Contributions" and find the article. (Notice that QM is FALSE – if QM were true, then, due to null oscillations diamond would spontaneously maintain the temperature of 95 centigrades – calculate it if you know QM well enough, take Y = 1200 GPa for diamond. Do not believe that the energy of null oscillations would not be transferred if they existed).
